You need to pass them with the handles structure array. In the function for the pushbutton if you define something like

handles.x=[]; handles.y=[];

they will be stored in the structure array handles that can be seen by all functions in a gui...

Also after you alter handles in a function you need to update the changes by using

guidata(hObject, handles);

If you don't do this other functions wont notice that the handles structure has been changed.
